/**
 * Gameshark code types: (based on AR v1.0)
 *
 * NNNNNNNN 001DC0DE - ID code for the game (game 4 character name) from ROM
 * DEADFACE XXXXXXXX - changes decryption seeds // Not supported by VBA.
 * 0AAAAAAA 000000YY - 8-bit constant write
 * 1AAAAAAA 0000YYYY - 16-bit constant write
 * 2AAAAAAA YYYYYYYY - 32-bit constant write
 * 30XXAAAA YYYYYYYY - 32bit Group Write, 8/16/32bit Sub/Add (depending on the XX value).
 * 6AAAAAAA Z000YYYY - 16-bit ROM Patch (address >> 1). Z selects the Rom Patching register.
 *                   - AR v1/2 hardware only supports Z=0.
 *                   - AR v3 hardware should support Z=0,1,2 or 3.
 * 8A1AAAAA 000000YY - 8-bit button write
 * 8A2AAAAA 0000YYYY - 16-bit button write
 * 8A4AAAAA YYYYYYYY - 32-bit button write // BUGGY ! Only writes 00000000 on the AR v1.0.
 * 80F00000 0000YYYY - button slow motion
 * DAAAAAAA 00Z0YYYY - Z = 0 : if 16-bit value at address != YYYY skip next line
 *                   - Z = 1 : if 16-bit value at address == YYYY skip next line
 *                   - Z = 2 : if 16-bit value at address > YYYY (Unsigned) skip next line
 *                   - Z = 3 : if 16-bit value at address < YYYY (Unsigned) skip next line
 * E0CCYYYY ZAAAAAAA - Z = 0 : if 16-bit value at address != YYYY skip CC lines
 *                   - Z = 1 : if 16-bit value at address == YYYY skip CC lines
 *                   - Z = 2 : if 16-bit value at address > YYYY (Unsigned) skip CC lines
 *                   - Z = 3 : if 16-bit value at address < YYYY (Unsigned) skip CC lines
 * FAAAAAAA 0000YYYY - Master code function
 *
 *
 *
 * CodeBreaker codes types: (based on the CBA clone "Cheatcode S" v1.1)
 *
 * 0000AAAA 000Y - Game CRC (Y are flags: 8 - CRC, 2 - DI)
 * 1AAAAAAA YYYY - Master Code function (store address at ((YYYY << 0x16)
 *                 + 0x08000100))
 * 2AAAAAAA YYYY - 16-bit or
 * 3AAAAAAA YYYY - 8-bit constant write
 * 4AAAAAAA YYYY - Slide code
 * XXXXCCCC IIII   (C is count and I is address increment, X is value incr.)
 * 5AAAAAAA CCCC - Super code (Write bytes to address, 2*CCCC is count)
 * BBBBBBBB BBBB
 * 6AAAAAAA YYYY - 16-bit and
 * 7AAAAAAA YYYY - if address contains 16-bit value enable next code
 * 8AAAAAAA YYYY - 16-bit constant write
 * 9AAAAAAA YYYY - change decryption (when first code only?)
 * AAAAAAAA YYYY - if address does not contain 16-bit value enable next code
 * BAAAAAAA YYYY - if 16-bit value at address  <= YYYY skip next code
 * CAAAAAAA YYYY - if 16-bit value at address  >= YYYY skip next code
 * D00000X0 YYYY - if button keys ... enable next code (else skip next code)
 * EAAAAAAA YYYY - increase 16/32bit value stored in address
 * FAAAAAAA YYYY - if 16-bit value at address AND YYYY = 0 then skip next code
